I had purchased a chandelier from an Amazon vendor; the tubes covering elec. connections to the bulbs were too short. Instead of sending back I purchased 12 thick brass colored washers. Geometric machine products machined them perfectly to fit over the elec. connections and raised the tube to the bottom of the bulbs so the bulb base no longer showed. A small project, but important to me. I am very satisfied with the quality of work and the cost involved.
